and sent another. The new one does ring the phone (once) much as the old one did (at one time) but then it crashes just like the old one. I suspect that if I keep ringing the phone whatever failed completely on the old one will fail on the new one. I guess people don't even test with mechanical ringers anymore...

Please log in for more thread options  Check out this link http://www.sandman.com/ringvoltbul.html and scroll down until you see "Adjusting an old 2500 set ringer to ring on lower voltages..." It all depends on if your ringer actually has the Bias spring adjustment. Cheap clone ringers usually don't have it. Mike Sandman's web site has quite a few devices available that can amplify the ring voltage if it is absolutely needed. | ||||||||||||||||

The only limit is how many ringers the 130VAC 20Hz supply in the KSU can drive, and they do make BIG supplies for big premises. Anyone know the REN for the input on a Western Electric 400G card? --<< Bruce >>-- | ||||||||||||||||

Please log in for more thread options I've got two shoeboxes (a 550 and a 550C, with the plastic lift off cover rather than a hinged door) and none of the 400-type cards installed specify an REN. And none of the 1A2 BSP handbooks I've got reveal that number, either. Maybe 400 cards got invented before REN was thought up and WE never went back to compute or measure that particular characteristic? Al | ||||||||||||||||

The current device is making the phone ring but it is crashing thereafter. The sequence is that I hear a relay click in the Cell2Tel, the phone rings once, I hear another relay click in the Cell2Tell, and then the Cell2Tel reboots. It's possible that the residual charge on the ringer's capacitor is too much for whatever the line is switched back too after the ring generator. It's clearly a pretty poor design.
